Description
Technical Field
The utility model relates to the technical field of video monitoring and security, in particular to an 8K high-definition video monitoring tester supporting SFP.
Background
With the development of science and technology, security video surveillance cameras have been implemented in 8K h.265 or h.264 image processing and transmission, and really realize high-definition video surveillance. Some camera manufacturers also realize merging of images of multiple lenses into a wider monitoring range, code streams transmitted by the cameras are as high as 8K, and 30fps real-time images are output under 8160x3616 resolution, while in installation and maintenance of the existing security video monitoring cameras, the existing test instrument tool can only realize 4K resolution 30fps image watching detection, and cannot test 8K (7680x4320, 8160x3616) high-definition cameras in formats such as H.264, H.265 HEVC, VP9, VP10 and the like with higher video compression ratios, and cannot be applied to installation and maintenance of 8K high-definition cameras.
When an engineer installs and maintains the monitoring camera, most faults occur in network transmission, so that the transmitted network or optical fibers must be detected to judge and eliminate the faults. Most of the existing monitoring systems adopt network cameras, network transmission is realized by arranging network cables for small-area monitoring, and network data is transmitted by arranging optical fiber cables for large-area monitoring.
With the rapid development of optical fiber communication, optical fibers are widely applied, the cost of the optical fiber cable is lower than that of a copper network cable, the communication is stable at a high speed, and meanwhile, the engineering cost is reduced. At present, long-distance communication over 2 kilometers is generally carried out by using single-mode optical fibers, short distance communication can be carried out by using multimode optical fibers, and single-fiber single-mode optical fibers are already common medium communication. The monitored image of the network camera for security monitoring engineering is compressed into a code stream of H.264 or H.265 and the like, and is communicated with a network video recorder communicated with a central machine room through a network cable or optical fiber equipment, and the network video recorder decodes, displays, stores and the like. At present, if the network video recorder is connected with the switch, if the distance is far away or for more stable network transmission, the SFP optical module is used for long-distance communication, for example, the SFP (a module) of the switch and the SFP (B module) of the network video recorder carry out high-speed stable communication. SFP optical communication as shown in fig. 1, various types of network cameras are connected to a monitoring host through an optical fiber network. In large-scale remote monitoring projects, optical fibers are basically used for communication, an optical transceiver or a few-port optical fiber switch is used at a front end, and a rack type optical transceiver or an optical switch is used at a machine room end to communicate with the front end so as to transmit network data. Some optical transceivers are fixed optical communication modules, and some optical transceivers are designed by using pluggable SFP optical modules for more flexible application, so that the optical transceivers can be suitable for various distance choices, such as 2km, 20km, 30km, 40km and the like, the scheme is flexible, and meanwhile, the cost is saved.
Aiming at the application requirements of the 8K high-definition camera, the existing security test tool in the current market has the following defects. First, image detection can only be performed for cameras below 8K, because chip decoding capability is insufficient and there is no corresponding software processing, and generally only camera images of 4K or lower resolution can be viewed, and images of higher resolution cannot be viewed. Secondly, the existing monitoring tester only receives network data through an RJ45 electric port, and a network cable is usually suitable for transmission within 100 meters; for a switch and an optical transceiver which are transmitted in a long distance, the communication cannot be directly connected, and the network camera image is watched.
SUMMERY OF THE UTILITY MODEL

The tester can enable engineers to select various SFP optical modules to be adapted to optical modules or optical receivers of the switchboard, so that the tester can be applied to more optical communication environments and has stronger compatibility.
